I have no idea if the bug has existed for a long time and I just hadn’t noticed it before, but the cadence symbol has a small graphic error. There are two small markers at the top left and bottom right that shouldn’t be visible.
ATV tvOS16, ZWIFT 1.29.0
Your eyes must be better than mine 
I´m riding 1,2m in front of a 55" TV. 
that might explain it!
The non drive side crank looks shorter too. 
You see the bike moving left to right whereas I see it moving right to left.
Still not resolved.
First world problem, I know, but it is so annoying to see this. Once discovered, I just can’t ignore it.
Still there with v1.50.2.
Still there with the new HUD (1.73.2)
Maybe not the best screenshot, but you can clearly see it, when you run Zwift on a 55" TV.
